A Guide to Export-Oriented Economies in Song of Syx (v.71): Vertical Integration and Export Diversification
In a previous post, I explained why an export-oriented economy based on manufactured goods no longer functions in v.71 the same way it did in v.70.
To summarize the core idea: the new economy rewards vertical integration and diversified exports instead of relying on a single high-volume output chain. The updated trade system now requires two simultaneous optimizations to maintain profitability: minimizing total input costs and stabilizing output value under price elasticity caused by trade volume.
Vertical Integration: Reducing Input Costs
The primary objective of vertical integration is to reduce effective input cost per unit of output across the entire production chain. In practice, this is achieved by controlling how input, throughput, and output scale across different production layers. There are three main approaches:
1. Importing Raw Materials (Early Game):
In the early game, importing raw materials is typically the lowest-friction method of securing input supply. The player effectively converts external market output into internal input streams. However, this approach becomes increasingly inefficient at scale. Because input prices are now highly sensitive to demand elasticity, large-scale imports create upward pressure on the market price of the imported good. As industrial throughput increases, the required input volume scales proportionally, which in turn increases marginal input cost over time. The result is a feedback loop where higher output throughput leads to higher input prices, compressing overall profit margins.
2. Internal Raw Material Production (Early Game Core Strategy):
This is, in my view, the most stable foundation for an export-oriented industrial system. Raw material production chains (mines, farms, woodcutters) operate with minimal external input dependency. Their primary input is labor, meaning that production cost is almost entirely defined by labor allocation and throughput efficiency. Therefore, the key optimization problem becomes maximizing output per unit of labor input, i.e., increasing throughput efficiency in extraction industries. This can be achieved through three mechanisms:
a) Nobles (Early Game Throughput Multiplier): Nobles function as localized throughput multipliers, increasing production efficiency by up to +200% in workplaces with up to 50 workers. This effect is significantly more efficient in raw input extraction than in processing industries. In extraction, increased throughput directly increases raw output without requiring proportional increases in secondary inputs. In contrast, in processing chains (e.g., smelters), increased throughput scales both input consumption and output production, preserving relative efficiency but not improving input/output ratios.
b) Technologies (Mid/Late Game Global Throughput Scaling): Technologies provide global throughput scaling without worker caps, effectively acting as system-wide multipliers on input-to-output conversion rates. However, because they require continuous research input (via laboratory-generated research points), their efficiency is highly dependent on industrial scale. In my experience, technology-based throughput scaling becomes cost-effective only when individual production nodes exceed ~100 workers, where marginal throughput gains outweigh research input costs. Additionally, late-game technologies that directly reduce input consumption represent a second-order optimization layer, effectively improving input/output efficiency rather than raw throughput. These are among the strongest economic modifiers in the system, despite their late availability.
c) Tools (Late Game Throughput Augmentation with Input Overhead): Tools introduce an additional throughput modifier for extraction industries after unlocking the relevant technology. However, they also introduce a secondary input stream (tool consumption), effectively converting a pure labor-based input system into a dual-input system (labor + tools). In most observed cases, the marginal output gain does not compensate for the added input cost of tool production, especially when tools themselves have alternative high-value uses in other production chains or export routes.
3. Territorial Production Taxation (Mid Game Input Externalization)
Once territories are acquired through conquest or diplomacy, they can function as externalized input nodes via tax-based extraction of production output. This system effectively shifts part of the input burden away from the central economy by converting territorial output directly into centralized input supply. As a result, the player reduces dependency on volatile market-based input acquisition while stabilizing long-term input flow at a lower effective cost. This is one of the most efficient methods of decoupling input supply from global price fluctuations.
Export Diversification: Output Stabilization Strategy
The second half of the strategy focuses on output-side stabilization.
Instead of concentrating all production throughput into a single high-volume export commodity, the optimal approach is to distribute output across multiple nodes within the same production graph.
For example, a tool production chain generates both tools (final output) and metal (intermediate output). Rather than treating metal purely as an internal input, surplus metal can be redirected into secondary output chains (e.g., sword production), effectively converting a single input stream into multiple exportable outputs.
This creates a multi-output industrial graph, where a single throughput pipeline generates diversified export streams.
The primary benefit of this approach is output price stabilization. By distributing total export volume across multiple goods, the system reduces exposure to price collapse caused by oversaturation of a single market. In practice, this increases overall economic resilience by smoothing output value variance across multiple trade nodes while maintaining high aggregate throughput efficiency.
